Dear @neonknight @harpo75 : The tread is about cartridges and not abouut other audio items.
The best place to buy vintge cartridges are ebay from Japanese sellers and Yahoo and other Japan sites.
The reason why we can get any vintage cartridges and some of them in NOS or mint condition is for what I posted.
Just comon sense and one of the post of neon confirm mine.
